Anybody used the nitrex box that supposedly removes ammonia, nitrites, and *nitrates* from the water. From what I can make out of the advertisement it does this using biological filtration somehow. Anyway, it sounds like it might be useful for salt water fish where nitrates are more critcal. That is, assuming it works? -- Ken Dalka (Bell Labs) ihnp4!ihlpg!dalka IE 2F-518 (312) 416-7437
